1 Claim.

The present invention relates to new and useful improvements in closures and more particularly to a closure in the form of a window or door having shutter means which can be readily opened or closed, depending upon the amount of air that is desired to pass therethrough.

An important object of the invention is to provide a ventilated closure of the character described which will not interfere with the conventional appearance of closures, and which can be readily regulated in inclement weather to permit room ventilation without likelihood of damage to fixtures.

Other objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents an outside elevational view of the improved closure,

Figure 2 is avertical sectional view taken substantially on a line 22 of Figure 1,

Figure 3 is a vertical sectional view, fragmentarily showing the invention in opened position,

Figure 4 is a perspective view showing one of the slats,

Figure 5 is a fragmentary perspective view of one of the shift rails,

Figure 6 is a horizontal sectional view through the closure with the slats in open position.

Referring to the drawings, wherein like numerals designate like parts, it can be seen that numeral 5 denotes, for instance, a door which is in the form of a frame defining an opening 6 in which the mechanism of the ventilating means is mounted. As is shown in Figure 2, the lower portion or sill at the lower end of the opening 6 has a short outwardly sloping bevel 1 and a longer inwardly sloping bevel 8. The first bevel I is adapted to accommodate the lowermost slat 9 while the bevels 8 accommodate the shift rails l0.

As can be seen in Figures 2 and 3, the outer side of the door 5 has a rectangular molding arrangement consisting of molding strips H, each of which has a tail portion 12 extending into a rabbeted portion of the door 5 where it is desirably secured in place.

Interposed horizontally between vertical side members H of the molding H are the slats 9 which when in closed position as shown in Figure 2 have ends at the lower edges thereof pivotally secured by pins l3 to the said side members a-a, while-the ends of the slats at the upper edges thereof are pivotally secured by pins M to the innermost edge portions of the shift rails l0, it being observed that these shift rails may be of ornate design so as to add to the appearance of the inside of the closure. Obviously, when the shift rails III are moved upwardly to the position shown in Figure 2, the slats are in interlapping relation, cured to the rails [0 being nestled in the rabbeted edge portions I5 of the edge portions of complementary slats which are pivotally securing to the molding members a-a.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed asnew is:

In a closure, a rectangular frame structure having side stiles and a bottom sill, said sill having a top beveled edge sloping downwardly toward one side of the frame and a pair of top slots adjacent said stiles, respectively, sloping downward toward the other side of the frame, a molding frame rabbeted into the inner edge of the frame structure on said one side thereof, a plurality of slats having ends pivoted adjacent lower edges of the slats to the sides of said molding frame for upward swinging into closed overlapping relation, said slats being swingable downwardly into open position, and a pair of upright slat operating rails on said other side of the frame adjacent said side stiles, respectively, and to which the ends of the slats are pivoted ad- Jacent their upper edges, said rails being movable upwardly and inwardly of said frame structure to close said slats, the slots accommodating the lower ends of the rails during such movement and providing clearance between said ends of the rails and said sill, the lowermost slat in the open position thereof abutting said top edge to establish the open position of all of the slats.
